Share Kunena posts to facebook

Kunena has some built in module positions you can use to do what you're looking for. We have a guide for how to add the social login buttons using these module positions:
www.sourcecoast.com/jfbconnect/docs/thir...tegration-for-kunena

You can do something similar with our JFBCSocialShare module where you can place it into one of the kunena-specific module positions. You could also use the JFBCSocialShare module to have the sharing buttons 'float' on the page like on the bottom of this site. If you'd like to do that, just let us know and we can point out the right documentation for setting that up.

Thanks,
Alex

could you, please, tell me about the 'float' thing...

Please see this page for the settings we use to show the JFBCSocialShare module on this page in the bottom right of the window.

and is it possible to have the text of the current post in it?

The JFBCSocialShare module does not have this functionality. You will need to do a template override of the module if you wish to add that, but it's not functionality that we provide.
